Kirsty Rogers, partner with DWF, said: “The man concerned worked from Wednesday to Friday and was not allowed time off in lieu for public holidays, though his colleagues who worked on Mondays got the day off.

“The court was asked to decide whether he was treated less favourably because he was a part-time worker. It concluded that the employer had not distinguished between part and full-time workers, but rather between those who worked Mondays and those who did not.

“While this case will rankle with many part-time workers, it could mean a considerable saving on holiday pay for some employers,” Rogers concluded.
